Description

Detailed Description of the Invention Invention #'i Surface and end outer surface of plywood or other plywood, board, or flashing material formed into a frame by using side core rods as a connecting material, as building materials or furniture materials This invention relates to a laminated board made of plywood having a surface layer made of a synthetic resin such as vinyl chloride, which is polymerized and bonded to form an end surface of an arbitrary shape.

Conventionally, as building materials or furniture materials, plywood and other plywood, boards, flashing materials formed by using side core rods as connecting materials to form a framework, and materials with synthetic resins or films pasted on the surface of these materials, etc. be. However, if these materials are simply cut surfaces or a decorative board is not pasted, the surface joints of each horizontal end face are separated and angular, so the decorative surface of the end face is It has the disadvantage that it is easily peeled off or damaged. In addition, when L was used, there were many disadvantages in terms of appearance and usage.

Therefore, the present applicant has already filed an application for a laminate A shown in FIG.
1162). Skeletal laminate board mu rj.

On the back side of a covering board 2 made of plywood with a surface layer 1 made of synthetic resin such as vinyl chloride bonded to the surface, the above-mentioned outer end @ surface width of an appropriate plate material 3 with the end outer surface 3 at - vertical, etc. A fitting @< is provided with a width corresponding to the circumference of a substantially semicircular arc having a diameter. Two covering plates are bent from the fitting groove 4 and polymerized and bonded to the plate material 3, and at the same time a separate covering plate is made!
It is polymerized and bonded to the II-shaped material 3. Then, the air formed at the junction between the covering plate 2 and the plate-like material 3 is filled with Tit@ resin (urethane, etc.) 7, and if TiC is used, the lamp is filled with an apricot IIL.
In order to reduce the amount of resin 7 filled, the rod-shaped material 8 is
It is inserted at 16 yen. Figure 1 shows the case where the rod-shaped member 8 is inserted.

This process is used to form a laminated board or the like whose direction is the rounded surface in the patent application filed by the present applicant in 9-0.

However, it goes without saying that when filling only the synthetic resin 7 into the cavity 116 formed at the threshold between the backing plate 2 and the plate-shaped material 3, it is necessary to insert the rod-shaped material 8 into the cavity ii6 circle. Synthetic resin 7
In the case of filling with GST resin, a sufficiently large hole must be constructed between the backing plate 2 and the rod-shaped member 8, and in the case of No. There was a drawback that the filling thickness of the synthetic resin 7 became large and the synthetic resin 7 foamed. this is,
As the synthetic resin 7 foams, the hardness of the foamed portion 111!1 decreases, and when the covering plate 2 is pressed from the outer surface, it becomes dented with a slight pressing force. This also weakens its action as an adhesive. In short, the product previously filed by the present applicant has the disadvantage that the surface rigidity and adhesive strength of the rounded surface portion of the backing plate 2 are reduced due to the foaming of the synthetic resin 70.

In view of the above-mentioned drawbacks of the laminate previously applied for by the present applicant, the present invention has been further improved and eliminated, and a concave groove for filling with synthetic resin is provided on the outer surface of the end of the plate-shaped material. In addition, a rod-like material is inserted into the gap formed between the cover plate and the plate-like material, and the gap between the covered plate and the rod-like material is set to 0.5 to 2.0-. By filling the above-mentioned concave grooves with IiL resin, we aim to form 14 arbitrarily shaped side parts IIl#, and provide a nine-layered board with excellent surface H degree and adhesive strength of the end face parts.
It is.

The W configuration of the present invention will be explained below based on the embodiments shown in the drawings.

Figures 2 and 4 show the laminate B of the first embodiment of the present invention. In the same figure, the surface layer 10 made by 9 companies [11 shows Ift made of hynyl chloride, etc., and the surface layer 10 made by JlilWI is shown in Table 1]
It is a plate-like material made by press-forming a cover plate made of plywood with fiK, 1lFi plywood or other plywood, or sawdust and applying T-pods or the like. Incidentally, as shown in FIG. 6, this plate-shaped lamp may be a flash material 14 in which a core rod 12 is framed by a connecting member 13.

Covering plate 9h, end outer surface 15 of plate material 11 on the back side thereof
A fitting groove 16 is provided at a position corresponding to the width a of the outer surface 15 of the end portion and the long width t. In this embodiment, the width of the lamp is set to be approximately equivalent to the circumference of a semicircular arc whose diameter is the width a of the outer surface 15 of the end portion. Further, a concave groove 18 for filling the resin 17 at the outer end of the plate material 11 is formed by cutting or laminating.

The laminate BH of this example is manufactured in the following manner.

That is, first, the covering plate 9 is placed on the upper surface side of the plate-shaped material 11, and the separately prepared covering plate 19 is placed on the downward side. The cover plate 19 is integrally constructed with the cover plate 9 and has a T-shape. Then, an adhesive is applied between the opposing surfaces of the plates 9 and 19 and the plate material 11 to polymerize and bond them together.
The fitting 11116 is partially folded and bent, and both end portions 91 (only one end is shown in FIG. 4) of the rear plate 90 are polymerized and adhered to the lower surface side of the plate material 11. These polymer adhesives are 1
A pressurizing type (not shown) having a built-in heating element is used to apply pressure and heat. In this way, the fitting groove 16 of the covering plate 9 has a width a'tm of the outer surface of the end of the plate material 11.
It is formed into an R surface having a substantially semicircular arc shape. After that, a rod-shaped member 21 having a semicircular cross section is inserted into the cavity @20 formed between the cover plate 9 and the plate-shaped member 11. The size of the rod-like material 21 is set so that the gap between the cover plate 9 and the skeleton rod-like material 21 is 0.5 to 2 degrees O.sup.2, as shown in FIG.

After the rod-like material 21 is inserted, a concave groove 18 is formed on the outer surface 15 of the end portion of the plate-like material 11, and a synthetic resin 17 such as urethane is filled. At 111117, it entered between the cover plate 9 and the rod-shaped material 20 through a narrow passage formed between the outer peripheral surface of the plate-shaped material 21 and the end outer surface 15 of the plate-shaped material 11. Then, the area is filled.

As mentioned above, in this embodiment, the gap between the covering plate 9 and the rod-shaped material 21 is extremely narrow with IIL of 0.5 to 2.0 square, and the synthetic resin 17 filled in the wrinkled portion is does not foam, but exhibits strong adhesive strength and sufficient hardness after curing. Further, the synthetic wood 5117 of the concave groove 18 penetrates into the structure C of the plate-like material 11 and hardens in that part, so that the plate-like material itself is strengthened, and the strength of the end face side portion of the laminate B is also increased. The reason for setting the above interval IIL between 0.5 and 2.0 is that if it is less than 0.5, it will be difficult to insert the rod-shaped member 21, and if it is more than 2,0 - , synthetic resin 17
This is because foaming occurs.

FIG. 5 shows a laminate C according to a second embodiment of the present invention.
It is. In this example, L7t% is used to form one rounded surface part and one straight part on the end face of the laminate 0. In this case, KH, a part of the coating [1GF] is extended and 1
The width of the fitting @ 16 of the covering plate 9 is set to the width of the outer surface of the end of the plate material 11 (thickness of the plate material 11) & the edge is also set slightly &%A@aK, and the fitting groove 16 above is set. Continuing to the above, the covering plate 19
A polymer 5B22 for polymerization is provided on the end face of the extended portion of
The wall thickness of this overlap g22 is made thicker than the wall thickness area of the fitting groove 16. This overlapping portion 2ZK taper portion z3 is provided. This tapered portion 23 is for easily overlapping with the end face of the extension portion of the covering plate 29. During the above-mentioned polymerization, the outer covering plate 9 may peel off the surface layer of the end face of the extended portion of the covering plate 19, and the tapered portion 2 may be removed from the right end of the fitting groove 16 in Figure 5.
Since the dimensions up to 3 are predetermined, the R [1 part 1 ratio of the covering plate 9 is uniquely determined. Further, this polymerization is carried out simultaneously when the covering plate 9, the plate material 11, and the covering plate 19 are superposed in the same manner as in the first embodiment. At that time, the overlapping part 22 becomes an area for applying adhesive, and the fitting l1
It is easy to distinguish it from 16. 24 is a member such as a tape attached to the surface (lower surface in FIG. 5) side edge of the cover plate 190. This member 24 is attached to the polymerized portion 22 during the polymerization.
This is to prevent the adhesive applied to the surface of the cover plate 19 from leaking out and staining the surface of the cover plate 19, and is peeled off and removed after polymerization and adhesion are completed. Further, after the polymerization adhesion is completed, the end @9b of the cover plate 9 is cut and removed at the position 2 in FIG. 5.

After tightening, the rod-shaped material 25 is inserted into the empty space s20 formed at the junction between the covering plate 9 and the plate-shaped material 11. put it here,
IIL is 0 between the covering plate 9 and the rod-shaped member 25.
．． 5 to 2.0 is the same as in the first embodiment (F). Finally, the concave groove 18 provided on the outer side of the end of the plate material 11 is filled with the fat 17. In this case too.

The synthetic resin 17fl passes through the narrow passage between the rod-like material 25 and the outer surface of the end of the plate-like material 11, enters into the interface between the cover plate 9 and the rod-like material 25, and is filled into the area. Synthetic tree in this part @
The process of foaming in step 17 is the same as in the first embodiment. A laminated plate C having an end face shape having one rounded part and one straight part is obtained.

In this method, according to the present invention #4, a concave groove for filling with synthetic resin is provided on the outer surface of the end of a suitable plate-shaped material or a flash material, and a surface layer made of synthetic resin such as vinyl chloride is provided on the surface. 1′ilJ#j of the outer surface of the cover plate made of plywood! .

A fitting groove with a diameter of 1-2 is provided in a portion corresponding to the outer side of the end of the plate-shaped material, and the fitting groove portion is bent and the covering plate is attached to the plate-shaped material, etc. After polymerization, a rod-like material is inserted into the gap Km formed between the covering plate and the plate-like material, and the gap between the rod-like material and the covering plate is set to 0.5 to 2.0 ■. death,
By filling the concave groove track with the compound IftflII oil, an end face of an arbitrary shape is formed, and there is no risk of the decorative surface of the surface layer peeling off, which is the case with conventional methods, and the appearance is often good. It is. Since the filled composite resin does not foam between the cover plate and the rod-like material, sufficient adhesive strength and hardness can be obtained at the end surface, resulting in excellent quality. Therefore, the scope of use as furniture materials, building materials, etc. is expanded.
